My ImageFormula RS40 'cannot find driver. Confirm whether it was installed properly'

combatwx — Thu, 06 Feb 2025 02:29:21 GMT

My RS40 had been working fine. When the Windows 11 came out recently, it stopped but I found the answer with that Citrix setting and it worked fine once more. THEN, last night I loaded an update for the RS40. Now whenever I try to scan something from within the program I get the error above.

I am running Windows 11 version 24h2 on a Dell 64bit system. I have uninstalled and reinstalled and restarted but no luck yet. Thoughts? THANKS!

To add some context, I FINALLY got the RS40 to be 'running properly' in Device manager, but still get this message above. OF NOTE...when I open up the 'Select Scanner' screen no scanners are listed. Help please!

Okay, I got it figured out. After multiple uninstalls and reinstalls, and running the configuration tool several times, I did a couple of things (my change management wasn't good so no way to tell what made the difference. I first went through steps to find what the name of a driver for the RS40 was. Then got THAT registered. THEN, I worked on determining why the scanner wasn't visible in the select scanner screen. Finally determined I needed a new TWAIN driver. I had ASSUMED that would be in the larger RS40 version 4 service pack, but apparently it wasn't. I downloaded JUST that driver and registered it. THEN I downloaded the latest Windows 11 service pack. Rebooted and was able to select the scanner. It works now.
